    Chapter 1. Router ATLAS 800 PLUS with router firmware The Frame Relay/Router option lets the ATLAS series of Integrated Access Devices act as a voice/data FRAD, a frame relay switch, and an IP router—in addition to the currently available bandwidth management and switch applica- tions.

  • Page 9: Chapter 2. Technology Overview

    Chapter 2 IP ROUTING Internet Protocol (IP) routing is performed at layer 3 of the Open System Intercon- nection (OSI) model. (Refer to the Frame Relay User Manual for a description of the OSI model.) The routing process determines the optimal path for data packets to travel and then moves the data packets along that path.

    Chapter 4. Configuration Overview and Examples Example 1: IP Routing Network—ATLAS as the Central-Site Router Example 1 (see Figure 4-2) depicts a typical IP routing network using an ATLAS as the central-site router. (This ATLAS unit is the ATLAS 800 relay upgrade.) The central-site ATLAS terminates a full T1 (F-T1) frame relay connection from the XYZ service provider, and the internal router terminates the IP traffic.
